Elsevier is a world-leading provider of information solutions that enhance the performance of science, health, and technology professionals.
All knowledge begins as uncommon—unrecognized, undervalued, and sometimes unaccepted. But with the right perspective, the uncommon can become the exceptional.
That’s why Elsevier is dedicated to making uncommon knowledge, common—through validation, integration, and connection. Between our carefully-curated information databases, smart social networks, intelligent search tools, and thousands of scholarly books and journals, we have a great responsibility and relentless passion for making information actionable.

Throughout the world, many native species inhabit agricultural landscapes. While natural habitats will form the cornerstone of conservation efforts in production-oriented environments, the success of these efforts will be enhanced by a greater understanding of the potential contribution of the increasingly modified countryside ('matrix') elements in these landscapes. Here, we investigate the relative occurrence of birds in some landscape elements (i.e. land-uses, vegetation types) common to agricultural environments around the world.
Targeting conservation payments to achieve multiple outcomes
This paper describes an environmental conservation planning model used in Queensland, Australia to purchase agreements on 66 sites covering 81,046ha at a cost of A$1.9 million. The model was used as part of a competitive tendering program called “NatureAssist”. The model maximises conservation benefit subject to a cost constraint using binary combinatorial optimisation. Multiple criteria analysis (MCA) is used to capture investor preferences and measure benefit over multiple outcomes. Conservation costs are drawn from real market data; i.e.
Applying portfolio optimisation to the harvesting decisions of non-industrial private forest owners
The non-industrial private forest owner's optimal harvesting and investment strategies are studied at forest holding level by including individual forest stands in an asset class portfolio. The forest owner can either clearcut mature stands and invest the capital in financial or real asset classes (bank deposits, government bonds, stocks, apartments) or postpone clearcutting and retain capital in standing trees.
Voting methods in strategic forest planning -- Experiences from Metsähallitus
Voting methods were used by Metsähallitus in a real strategic participatory planning case in a regional working group context. The general aim of the study was to find out whether learning and collaborative decision making could be adequately supported by using the voting methods in the regional stakeholder group.
Multiple site tower flux and remote sensing comparisons of tropical forest dynamics in Monsoon Asia
The spatial and temporal dynamics of tropical forest functioning are poorly understood, partly attributed to a weak seasonality and high tree species diversity at the landscape scale. Recent neotropical rainforest studies with local tower flux measurements have revealed strong seasonal carbon fluxes that follow the availability of sunlight in intact forests, while in areas of forest disturbance, carbon fluxes more closely tracked seasonal water availability.
